Moisture penetrating a photovoltaic (PV) module may react with the metallic components causing corrosion. In addition, acetic acid which is produced by hydrolysis of ethylene vinyl acetate (EVA), the most common encapsulant, may further degrade metallic components.
When the c-Si photovoltaic (PV) module is operating in the new degradation mode, the electroluminescence (EL) dark area showed an increase in the series resistance that spreads around the bus bars. To understand metallization corrosion, a high-temperature and high-humidity test was conducted using PV modules.
Conferences > 2022 IEEE 49th Photovoltaics Corrosion is a major end-of-life degradation mode in photovoltaic modules. Herein, an accelerated corrosion test for screening new cell, metallization, and interconnection technologies is presented. The top glass and encapsulation layers were removed from modules to expose the solar cells.
The lifetime of a photovoltaic (PV) module is influenced by a variety of degradation and failure phenomena. While there are several performance and accelerated aging tests to assess design quality and early- or mid-life failure modes, there are few to probe the mechanisms and impacts of end-of-life degradation modes such as corrosion.
This study investigates the effect of corrosion of the metallization containing lead tellurite glass frit used in solar cells due to acetic acid. When the c-Si photovoltaic (PV) module is operating in the new degradation mode, the electroluminescence (EL) dark area showed an increase in the series resistance that spreads around the bus bars.
The relationship between the acetic acid and the degradation of the PV module, in which the metallization paste contains PbO-TeO 2 glass frit, was investigated. The EL dark area spread from the bus bars during the high-temperature and high-humidity test.
